I’m a fan of breakfast waiting for me when I arise. Having this Crustless Spinach Quiche in the refrigerator is a delicious way to have a high protein, low carb breakfast ready to go even before my tea is brewed!

I’ve never been a proponent of starting my day with a carb heavy, sugary breakfast. That just puts me in the mood to crawl back into bed. This crustless spinach quiche can easily be made ahead and then gently zapped in the microwave for an almost instant breakfast!

This vegetable quiche is stuffed with spinach, of course, two cheeses, garlic and mushrooms. But you can shake up the ingredients anyway you’d like. How about some roasted bell peppers and artichokes? The hubby isn’t a fan of either mushrooms or artichoke hearts, but he’d love some cooked Italian sausage or bacon added to his version.

Using all cheddar cheese or adding some Swiss into the mix would be nice, too. Try this quiche with your favorite cheeses.

Quiche or Frittata?

A quiche is made with a mixture of eggs and milk, cream or half and half. The texture is softer and creamier than what you’d find with a traditional frittata, which can contain many of the same add ins, but no milk. A frittata is more like a skillet omelet.

Also, a frittata is typically started on the cook top, then finished off in the oven. A quiche is just baked, though some of the vegetable components are cooked in a skillet first to brown and soften, like with this crustless spinach quiche.

Reheating Leftover Quiche

One thing you don’t want to do is zap your leftover quiche slice into a rubbery mess. High heat will over-tighten the protein threads pushing the water out of the web of amino acids causing the eggs to become tough.

  • You can reheat your quiche at 325º for about 20 minutes or until warmed through the middle. Since this quiche does not have a crust it may not need as much time as a crusted version.
  • Alternatively, you can gently reheat a slice of quiche at 50% power at 20 second increments until warm. The times will vary depending on the power of your microwave.
  • Bringing the quiche out of the refrigerator and letting it sit on the counter for 20+ minutes to get the chill off will lessen the chance of overcooking when using the microwave.

If you’re looking for other breakfast ideas, my family loved these Egg Muffins in Ham Cups, Gruyere Spinach Strata, and this Sun Dried Tomato Spinach Quiche. I’ve also had my eye on this Slow Cooker Fritatta with Artichoke Hearts, Roasted Red Pepper and Feta as well as this Western Omelet Quiche.

  • Cook Time: 55 minutes
  • Total Time: 1 hour 10 minutes
  • Yield: 4 servings 1x
  • Category: Breakfast, Brunch
  • Method: Baking
  • Cuisine: American


1 tablespoon olive oil
8 ounces white mushrooms, sliced
1 clove garlic, minced
10 oz box frozen spinach, thawed and squeezed dry
4 eggs
1 cup milk, I used 2%
1/4 cup sharp cheddar, diced
1/2 cup shredded Gouda cheese
Salt and pepper to taste, I used 1/2 teaspoon kosher salt and 1/4 teaspoon freshly ground black pepper


Preheat the oven to 350ºF. Grease a 9-inch pie plate and set aside.

Add olive oil to a non-stick skillet and saute the mushrooms, garlic, and a pinch of salt until mushrooms are lightly browned and have given off all their liquid. Add the spinach and mix and heat for a minute to remove any excess moisture.
Place the spinach mixture in the bottom of the pie dish, followed by the cheddar chunks.
In a medium bowl, whisk together the eggs, milk, salt and pepper.

Pour the egg mixture into the pie plate. Top with the shredded Gouda cheese.
Bake for 45-55 minutes, or until the top is golden brown (ovens may vary). Slice and serve.

  1. I love quiche, this is perfect for weekend brunch!

  2. A perfectly delicious and low carb meal! I need to bake one soon. Thanks for sharing, Liz.

  3. Boy this sounds good! I haven’t made one in a while… Adding to my list-thanks:@)

  4. Sounds and looks delicious, Liz! I haven’t made quiche in a long time and this is a must try. Thanks!

  5. I usually buy my quiche from Delifrance. Wish I can make one too! xoxo 

  6. This is just the kind of breakfast dish that has me jumping out of bed in the morning! Though I love quiche, most of the time I don’t want to be eating pie crust for breakfast. 😉 So this crustless version is absolutely perfect!

  7. Although I would prefer a quiche with crust, this is a more desirable nutricious version and much more calorie – friendly. I can make myself adjust occasionally. It would be nice not to get up in the morning and make oatmeal. (which is what I do every single morning) I think this winter, when I have more time, I will go out on the proverbial limb and diversify!.

  8. Great idea! So many people don’t want carbs, so this is brilliant! Love the filling.
